Codes: +AT solution annealed, +A soft annealed, +PE peeled, +C cold drawn, +LC skin passed. Diameter ranges are over the first figure up to and including the second. No reduction of area is specified for +AT+C. For non-circular sections the properties are agreed between manufacturer and purchaser. Printed as X03Cr17Ni13Mo3 in Table 11; Tables 10 and 15 give X03Cr17Ni12Mo3.
